1. Phreatomagmatic eruption
Recently, a new island emerged near Japan's Ogasawara island chain after an undersea volcano erupted.
About Phreatomagmatic eruption:
- A new island near Japan's Ogasawara island chain was formed by phreatomagmatic eruption.
- It is an eruption that involves both magma and water. It typically interacts explosively leading to concurrent ejection of steam and pyroclastic fragments.
- Phreatomagmatic ash is formed by the same mechanism over a wide range of basic and acidic compositions. A blocky and uniform crust with low vesicle content is formed.
- Deposits from phreatomagmatic eruptions are thought to be better classified and finer-grained than those from magmatic eruptions. This is the result of higher fragmentation of phreatomagmatic eruptions.
Key facts about Ogasawara Islands
- The Ogasawara Islands are located in the North-Western Pacific Ocean.
- It is also known as Bonin Islands.
- It is a volcanic arc comprising more than 30 islands and islets.
- The landscape is dominated by subtropical forest types and sclerophyllous shrublands surrounded by steep cliffs.
- It is one of the famous UNESCO World Heritage sites of Japan.
2. Non-melanoma skin cancer
As per the World Health Organization, about one in every three deaths that take place from nonmelanoma skin cancer is reportedly caused by working outdoors under the sun.
Highlights of the report:
- In 2019, approximately 6 billion people of working age (15 years and older) were exposed to solar ultraviolet radiation while working outdoors, accounting for 28 per cent of all working-age people.
- In the same year, nearly 19,000 people in 183 countries died from non-melanoma skin cancer as a result of working outside in the sun. The majority (65 per cent) were men.
- Governments should establish, implement and enforce policies and regulations that protect outdoor workers from sun-induced skin cancer
About Non-melanoma skin cancer:
- It refers to a group of cancers that develop in the upper layers of the skin.
- The main types are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
- The main cause is ultraviolet light, which comes from the sun and is used in sunbeds.
- It is more common in older people, but younger people can also get it.
- Symptoms
- The main symptom of non-melanoma skin cancer is a growth or unusual patch on the skin, but it's most common in areas exposed to the sun, such as head, face and ears neck and shoulders etc.

4. Insurance Surety Bond
National Highways Authority of India (NHAI) has accepted Insurance Surety Bond for the monetization program of the upcoming bid of Toll Operate Transfer (TOT) Bundle 14.
Why in news?
- It is the first time this innovative instrument (Insurance Surety Bond) is being utilized as a Bank Guarantee (BG) in the road infrastructure sector for monetization of bids.
- NHAI has been working closely with Highway Operators Association of India (HOAI), SBI General Insurance and AON India Insurance to implement this initiative.
About Insurance Surety Bond:
- These bonds can be defined in their simplest form as a written agreement to guarantee compliance, payment, or performance of an act.
- These are instruments where insurance companies act as ‘Surety’and provide the financial guarantee that the contractor will fulfil its obligation as per the agreed terms.
- Surety is a unique type of insurance because it involves a three-party agreement.
- The three parties in a surety agreement are:
- Principal:The party that purchases the bond and undertakes an obligation to perform an act as promised.
- Surety:The insurance company or surety company that guarantees the obligation will be performed. If the principal fails to perform the act as promised, the surety is contractually liable for losses sustained.
- Obligee:The party who requires and often receives the benefit of the surety For most surety bonds, the obligee is a local, state or federal government organisation.
- Significance
- It will act as a security arrangement for infrastructure projects and will insulate the contractor as well as the principal.
- The product gives the principal a contract of guarantee that contractual terms and other business deals will be concluded in accordance with the mutually agreed terms.
- In case the contractor doesn’t fulfil the contractual terms, the Principal can raise a claim on the surety bond and recover the losses they have incurred.
- Unlike a bank guarantee, the Surety Bond Insurance does not require large collateral from the contractor, thus freeing up significant funds for the contractor, which they can utilise for the growth of the business.
- The product will also help in reducing the contractors’ debts to a large extent, thus addressing their financial worries.

What are El Nino and La Nina?
- El Nino and La Nina events occur every two to seven years on average (El Nino is more frequent than La Nina), but not on a regular basis, and together are referred to as the El Nino-Southern Oscillation (ENSO) cycle by scientists.
- El Nino is typically known as the warm phase(a band of warmer water spreading from west to east in the equatorial Pacific Ocean), and La Nina is identified as the cold phase (a band of cooler water spreading east to west) of ENSO.
- What happens during El Nino?
- During El Niño, trade winds weaken.
- Warm water is pushed back east, toward the west coast of the Americas.
- Rainfall increases drastically in Ecuador and northern Peru, contributing to coastal flooding and erosion.
- As El Niño brings rain to South America, it brings droughts to Indonesia and Australia.
- The eastward movement of oceanic and atmospheric heat sources causes unusually severe winter weather at the higher latitudes of North and South America.
8. What are Vampire Viruses
Several ‘Vampire Viruses’ have been recently discovered on US soil for the first time.
About Vampire Viruses:
- They are pathogens that latch onto other viruses in order to replicate themselves.
- They emerge when a bacteriophage attaches to a soil-based virus, utilising its "life" for independent survival.
- This viral relationship between two pathogens is called a satellite and a helper. The satellite is the infectious strand that relies on the helper for support through its life cycle.
- Satellites depend on both their host organism and helper virus to complete its life cycle.
- The satellite virus depends on the helper virus to build the protective shell that covers its genetic material, called a capsid or to help it replicate its DNA.
- Most satellite viruses contain a gene that allows them to integrate into the host cell’s genetic material after they enter the cell.
- This enables the satellite to reproduce whenever a helper enters the cell from then on.
- The host cell also copies the satellite’s DNA and its own when it divides.
What is a Bacteriophage?
- Bacteriophages (BPs) are viruses that can infect and kill bacteria without any negative effect on human or animal cells. They are comprised of a protein capsule around an RNA or DNA genome.
- For this reason, it is supposed that they can be used, alone or in combination with antibiotics, to treat bacterial infections.
